MULTIPLE CHOICE

 

BASIC CONCEPTS

 

1. Which statement regarding primary open-angle glaucoma (POAG) is true?

a.	It is most common in children.
b.	The major cause is trauma to the eye.
c.	The problem usually affects both eyes.
d.	The first symptom is chronic eye pain.

 

 

ANS:  C

POAG is the most common form of glaucoma and is much more common in older adults. It does not occur as a result of trauma and usually affects both eyes, although one eye may be affected to a greater degree than the other.

2. Which term means constriction of the pupil of the eye?

a.	Miosis
b.	Punctum
c.	Glaucoma
d.	Mydriasis

 

 

ANS:  A

Miosis means constriction of the pupil, mydriasis means dilation of the pupil, glaucoma is an eye disease that is caused by increased intraocular pressure, and punctum is the opening in the lower lid that drains tears into systemic circulation.

3. Which drug group for glaucoma should be avoided in children long-term because they slow growth?

a.	Adrenergic agonists
b.	Beta blockers
c.	Carbonic anhydrase inhibitors
d.	Prostaglandin agonists

 

 

ANS:  C

Carbonic anhydrase inhibitors are not recommended for children who have glaucoma in one or both eyes because drugs from this group can slow growth when used long-term.

Children have a limited time for normal growth. Once the growth plates in the long bones close, growth in height does not occur. Carbonic anhydrase inhibitors slow children’s growth and contribute to shorter stature in final adult height.

4. What is the main problem of glaucoma?

a.	Cloudiness of the lens
b.	Cloudiness of the cornea
c.	Increased intraocular pressure
d.	Increased intracranial pressure

 

 

ANS:  C

Glaucoma is a problem related to increased intraocular pressure that can put so much pressure on ocular blood vessels, photoreceptors, and the optic nerves that blindness results. It does not affect the lens, the cornea, or the intracranial pressure.

5. Where in or on the eye should eye drops be placed?

a.	Under the upper lid
b.	In a pocket of the lower lid
c.	Directly over the center of the eye
d.	In the corner of the eye closest to the nose

 

 

ANS:  B

To ensure that eye drops remain in the eye long enough to produce their intended actions, the individual administering the drops should gently pull the lower lid down slightly and create a small pocket and then place the drops into this pocket.
